A lot of effort has been devoted lately to the introduction of Solid Oxide Fuel Cells (SOFCs) in the energy production market toward a low carbon economy. SOFCs present a lot of advantages, compared to conventional thermal engines, such as high energy efficiency, lower environmental footprint, fuel flexibility, better modularity, etc. Different manufacturing methods have been investigated up to date such as CVD, PVD, tape casting, screen printing, thermal spraying etc. Recently thermal spray techniques are becoming industrially applicable for the production of different types of cells mostly due to the materials flexibility, lower cost, faster production rates, scale up capacity, ability to coat complex geometries, deposition of efficient layers with controlled composition and porosity etc. In the present work, porous LSM-YSZ coatings using different thermal spray techniques (APS and LPS) deposited on in-house developed thin and dense YSZ electrolyte planar substrates are evaluated. Commercial cathode powder was used for the atmospheric plasma sprayed coating deposition. Stable LSM-YSZ suspensions were studied in terms of homogeneity, low viscosity, sedimentation and re-dispersability after long shelf life in order to be employed as feedstock in Liquid Plasma Spray. Differences and similarities of the different approaches concerning coatings minimum thickness, microstructure, quality, adhesion etc. are highlighted. Finally, as prepared symmetrical LSM-YSZ/YSZ cells exposed in air at different operation temperatures were electrochemically characterized by electrode polarization measurements and AC impedance spectroscopy studies.
